How can I resize full screen banner images on the Hulk theme?

[Blossom_222]

Hi, I’ve been trying to figure out a solution to this problem for a while now and wondered if anyone could help.
Im using the Hulk theme and the homepage looks great on a mobile and desktop, however in full screen mode the 3 banner images are way too big. Is there a bit of code that would fix this?

Thanks in advance.
